Problems

  • !
    Expires in 20 days
    Registration · The registration expires on 2026-11-11. Make sure it is renewed.
    #3
  • !
    No IPv6
    Delegation · None of the nameservers has an IPv6 address, so IPv6-only resolvers can't reach them.
    #13
  • !
    Not signed
    DNSSEC · The zone is not signed with DNSSEC, so answers can be spoofed. Enable DNSSEC at your DNS provider and publish the DS record at your registrar.

Problems

  • ✗
    Policy: none (monitoring only)
    DMARC · DMARC policy is set to 'none', which only monitors but doesn't protect against spoofing. Consider upgrading to 'quarantine' or ideally 'reject'.
    #4
  • ✗
    Policy not reachable
    TLS · The MTA-STS record exists but the policy could not be fetched, so senders ignore MTA-STS: Get "https://mta-sts.ac-nantes.fr/.well-known/mta-sts.txt": context deadline exceeded (Client.Timeout exceeded while awaiting headers).
    #33
  • ✗
    DMARC not strict enough for BIMI
    BIMI · Mail clients will not show the logo. BIMI requires DMARC p=quarantine or p=reject (now p=none), a subdomain policy other than sp=none.
    #39
  • !
    Not enabled
    DNSSEC · DNSSEC is not enabled for this domain. Consider enabling DNSSEC to protect against DNS spoofing attacks.
    #8
  • !
    Hosts without IPv6
    MX · The following MX hosts could not be resolved to IPv6 addresses: msg-a85.education.gouv.fr, msg-b85.education.gouv.fr
    #11
  • !
    1024-bit DKIM key
    DKIM · 1024-bit RSA keys are the minimum and are considered weak today: default (1024 bits). Rotate to a 2048-bit key.
    #23
  • !
    No certificate (a=)
    BIMI · The logo is published without a Verified Mark Certificate. Gmail and Apple Mail only show BIMI logos with a VMC or CMC; Yahoo shows it without one.
